This series addresses several issues discovered in the drop_monitor subsystem: Patch 1 adds missing tracepoint unregistration synchronization to the net_dm_trace_on_set() error unwind path, preventing in-flight probes from scheduling work after the module reference has been dropped. Patch 2 resolves a race condition during monitoring teardown where per-CPU timers can be re-armed after deletion if a concurrent worker encounters a memory allocation failure, switching to timer_shutdown_sync(). [...]

- [net,2/4] drop_monitor: use timer_shutdown_sync() to prevent timer rearming during teardown
